design=donau_inverse

I'm using this tag for the donau-type, where the wider arms are on the top with two isolators and one isolator on the bottom arms. One system in shape of a 'v'. So another possible name/symbol would be 'w' or 'vv' for two systems. Here is a good example:. 292829257 292829257 see ESRI or Bing background. --Bahnpirat (talk) 14:37, 28 September 2021 (UTC)

Didn't know about such a design. Could you check if I drew the icon right? Donau: , inverse donau: . Enzet (talk) 05:33, 28 September 2021 (UTC)

The symbol is fine and fits good. I know only 3 lines with this design. All in Thuringia, Germany. More regular (but only on short distances) would be a two-level-tower with top level 2x 3-phase 110 kV, 50 Hz and the lower level would be 2x 2-phase 110 kV, 16.7 Hz to supply energy to trains. (substation=traction). The design looks the same. Thanks. --Bahnpirat (talk) 14:37, 28 September 2021 (UTC) There is also one tower in Brazil in the State of São Paulo and it has line_management = transpose.Owen C 200 (talk)

Slovak "Macka" tower and it's design

Tower design informally called "mačka" is pretty common in Slovakia (also saw few of them in the Czech Republic). It is carrying one circuit with conductors at two levels and in triangular arragment - suspension, anchor tower. How should I tag this design? design=two_level, design=triangle (conductors only at two levels and in more symmetrical layout) or design=y-frame (there is a horizontal cross-beam between top structures). --Chiak (talk) 16:33, 30 April 2022 (UTC)

two poles through-bolted

How to tag two poles that are bolted together and then have an arm https://westnordost.de/p/92284.jpg I don't think it counts as H frame (pi pole) because there's no gap between them but maybe that's okay. It's basically like a pole but there are two so I guess it should be power=tower? Thanks TrekClimbing (talk) 22:18, 8 September 2022 (UTC)
